The ratio of rise over run is related to which aspect of a building?

  1. Brick masonry walls

  2. Chimney stacks

  3. Noiseless floors

  4. Roof gradients

  5. Ventilation shafts

  6. Windows alignment

The correct answer is: Roof gradients

The ratio of rise over run is related to roof gradients. This ratio is commonly referred to as the pitch of a roof, and it represents the slope or steepness of the roof surface. A steep pitch means a larger rise over a shorter run, while a shallow pitch means a smaller rise over a longer run. Understanding and calculating the pitch of a roof is crucial for determining the drainage of rainwater, the load-bearing capacity of the roof, and also for aesthetic purposes. Roof gradients play a key role in the overall design and construction of a building's roof.
